Haori36-MX: common questions

What microcontroller does the Haori36-MX use?

The Haori36-MX is built around the RP2040_Zero, from the RP2040/RP2350 family.

How big is the Haori36-MX PCB?

The Haori36-MX measures 213.7 × 76.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Haori36-MX?

109 components, from 4 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Haori36-MX design files?

From the penk/Haori36-MX repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Haori36-MX design in my own project?

Yes, under the terms of its MIT license, which penk chose for the repository.

Can I test firmware for the Haori36-MX without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
